Primary Examiner-Banjamin Hersh Assistant Examiner Robert R. SongAttorney-Walter Becker ABSTRACT: A shipping carton especially for largesurface filter layers, which comprises a main carton sectioncorresponding in cross section and longitudinal section to theconfiguration of a plurality of stacked filter layers to be shipped,said main carton section having a top and abottom wall and two sidewallsand being open at both ends which latter are closed by cap shaped endsections provided with handle means while roller means are placed on theoutside of said bottom wall for facilitating the transport of saidcarton.

The present invention relates to a package or container for shippinglarge surface filter layers. Prefabricated filter layers of smallerdimensions for filter presses are stacked for dispatch and placed into apackage which customarily consists of an envelope of wrapping materialor of a carton.

, For large area rectangular filter layers, especially for socalledfolding layers which are likewise dispatched in stacked condition, thesimplepackage as referred to above is unsuitable because it permitsdamage to the valuable layers, especially at the corners and edges. Asolid wrapping or packaging employed for this reason has thedisadvantage that it is very expensive and, due to the considerablestack weight and the large dimensions of the layers, is extremelydifficult to handle and to transport. 7 7

It is, therefore, an object of the present invention to provide a way ofpackaging large surface rectangular filter layers which will overcomethe above-mentioned drawbacks.

It is another object of this invention to provide a new way of packaginglarge surface rectangular filter layers which will require a minimum ofmaterial while affording satisfactory protection for the layers.

Still another object of this invention consists in providing a packageor dispatch container for large surface rectangular filter layers whichcan easily be handled and transported.

These and other objects and advantages of the invention will appear moreclearly from the following specification in connection with theaccompanying drawings, in which:

FIG. 1 shows a front view of the dispatch container according to thepresent invention;

FIG. 2 shows a side view of the dispatch container of FIG. 1;

FIG. 3 is an isometric view of a cap for use in connection with thepresent invention;

FIG. 4 is an isometric view of a supporting roller for use in connectionwith the dispatch container of FIG. 1; and

FIG. 5 shows a detail of the dispatch container of FIG. 1. Based on theconsideration that the quantity of wrapping material necessary for thestability of the wrapping'and' thereby the price for such large wrappingor dispatch con tainer may be kept particularly low if means areprovided for handling and transporting the dispatch container or packageand the said means are well engineered, the present invention suggests'a'container particularly suitable as a one-way container whichcomprises a foldable carton adapted to receive stacked filter layers.More specifically the said folding carton has two oppositely located endfaces respectively provided with caps equipped with handles and adaptedto be slipped onto the carton, whereas a further end face is providedwith two or more serially arranged spaced rollers which are connected tothe carton by means of bands surrounding said carton in longitudinallytransverse direction According to a preferred embodiment of theinvention, each cap is equipped with two handles connected to the frontwall of the cap, and each roller is connected to a U-shaped guidingmeans corresponding to the width of the end face of the carton, saidguiding means being adapted to be placed upon the end face of thecarton. 1

Referring now to the drawing in detail, it will be noted from FIG. 2that a plurality of rectangular filter layers 10, for instance foldinglayers, for large surface filter presses of heretofore known design areassembled inva-pile or stack and are placed into a folding carton 11conforming with the dimensions of the pile of filter layers. The cartonll encases the pile of filter layers on all sides. For purposes ofprotecting the corners of the carton 11 which are particularlyendangered during transport and also to protect the layers 10, each ofthe two I oppositely located short'end faces of the carton are providedwith a cap 12 which expediently consists of cardboard. The

cap 12 which is shown in greater detail in FIG. 3 is as to width andthickness dimensioned in conformity with the short carton end face andforms a hollow body. The cap 12 which is thus adapted to be slipped overthe foldin carton 11, advantageously has two .handles 13. The han les 13are spaced may consist of wood or any suitable synthetic material. isconnected to a carrier member 15 preferably made of a short sheet metalmember of U-shaped cross section. The carrier profile corresponds to thethickness of the carton l1 and is adapted to be placed upon a long endface thereof.

The caps 12 and rollers 14 including the carriers 15 are connected tothe respective end faces of the carton by means of closure bands 16, 17which extend in longitudinal and transverse direction of the carton forclosing the same. More specifically, for the oppositely located caps 12there are provided two longitudinal bands 16 and for each roller 14there are provided two transverse bands 17. Advantageously, the rollers14,15 are arranged within the area of the caps 12. For purposes ofincreasing the strength of the rollers and saving a vertical closureband 17, one end of a roller carrier 15 (FIG. 5) may be surrounded bythe adjacent cap 12. For the nonenclosed end of the roller carrier 15there'will then be required only one vertical closure band 17.

While as closure bands customary steel bands may be employed, it isparticularly advantageous to use elastic textile ribbons 16, 17 asclosure bands; which can easily be cut by scissors. In this way, thecarton can beopened immediately so that the caps 12 and rollers 14 canbe removed from the carton 11.

,In this manner the opening of the carton can be effected without usingany tools, which are liable to damage the filter layers. 7

It is, of course, to be understood, that the present invention is, by nomeans, limited to the particular constructions shown in the drawings,but also comprises any modifications within the scope of th appendedclaims.

lclaim:

1. A shipping carton, especially for large surface foldable U shapedfilter layers, which comprises: a single piece main carton sectionforming a tubular member corresponding in cross section and longitudinalsection to the configuration of a plurality of stacked filter layersreadily bendable both in flat horizontal and also upstanding verticalstorage positions to be shipped edgewise therein, said main cartonsection having a top and a bottom wall and two sidewalls and being openat both ends, two end sections, each having an end wall and a flangearound the periphery of said wall to form a cap, said end walls havinghandles and said caps being respectively placed over the end portions ofsaid main carton section and closing the open ends thereof with saidflanges surrounding and reenforcing the ends of said main cartonsection, roller means on the outside of said bottom wall and spaced fromeach other in the longitudinal direction of said carton, each rollermeans comprising a carrier member U-shaped in cross section with thebottom wall of said: main carton section mounted therein, and band meanswould longitudinally about said carton to secure said end sections tosaid main section and other band means wound transversely about saidmain section and the flanges of said end sections and about said carriermembers to secure said carrier members to said main section and toreenforce said flanges of said end sections so that the handles and endsections can support said carton for transport.

2. A shipping carton according to claim 1, in which one end of each ofsaid channel members is received and surrounded by the respectiveadjacent cap section, and in which the same band means which firmlyconnects said roller means to said main carton section also connects andholds the respective adjacent cap section to said main carton sectionsimultaneously.
